Rebirth is not the same as reincarnation. Reincarnation refers to the belief that a soul at the termination of life enters a new physical body. Jainism, Hinduism & Sikhism may believe in reincarnation where as original Buddhism (before the later day variations) believes in rebirth.

I'm interested in knowing the proofs of Karma theory & rebirth presented by Buddhism.

In Buddhism, kamma & rebirth is a doctrine of moral efficiency. The teachings state:

And what is the right view with effluents, siding with merit, resulting in acquisitions?
There are fruits & results of good & bad actions (kamma). There is this world & the other worlds. There are spontaneously reborn beings [due to actions/kamma]...
MN 117

For example, a free man robs a bank, is caught & is reborn as a prisoner is a prison. This is the proof of kamma & rebirth, where the free man later takes spontaneous (immediate) rebirth as a prisoner & treated like an animal in a zoo.
Or a normal person takes drugs & becomes a drug addict & then a thief or prostitute. Here, the humane being is reborn in a ghost & animal birth. They are reborn as a ghost because they always must search for drugs, never content, & they are reborn as an animal because they must always perform bestial depraved acts to obtain money for drugs. This is the proof of kamma & rebirth.
Buddhism teaches at least five destinations of rebirth due to kamma (motive & action), namely, humane (sane), godly (exalted), ghost (addiction), animal (lack of self-control) and hell (suffering), as follows:

Intention, I tell you, is kamma. Intending, one does kamma by way of body, speech & mind.
Sense contact is the cause by which kamma comes into play.
And what is the diversity in kamma? There is kamma to be experienced in hell, kamma to be experienced in the realm of common animals, kamma
to be experienced in the realm of the hungry shades, kamma to be
experienced in the humane world, kamma to be experienced in the world
of the gods. This is called the diversity in kamma.
AN 6.63

In Budddhism, the word 'birth' ('jati') refers to 'production' ('abhinibbatti') of the idea or view of a 'person' ('puriso'), 'self' ('atta') or 'being' ('satta'). 'Re-birth' is the continued production of these ideas or views of 'self', 'persons' or 'beings', which generally occurs due to 'kamma' ('motive & action').
For example, kamma is made to successfully make money. Here, the mind is 'reborn' as a 'god', thinking: "I am rich; I am successful; I am special; I am upper class".
Then later, there is a collapse in the stock market & loss of wealth. The same person in reborn in hell (suffering), thinking: "I am poor; I am a failure; why didn't I do this; why didn't I do that!".
Each thought of "I am" is a "birth' ("jati"), created by the craving & motive that drives kamma (intentional actions).
This is kamma & rebirth. People are reborn into different mental states of self-identification due to their kamma (motives & actions). They are reborn as rich, poor, husband, wife, divorcee, widow, etc, due to their kamma that leads to self-identifying. The teachings say:

The craving that makes for further becoming — accompanied by passion & delight, relishing now here & now there — i.e., craving for sensual
pleasure, craving to be, craving not-to-be: This, friend Visakha, is
the origination of self-identification described by the Blessed One.
MN 44

Each act of 'self-identification' is a 'birth' or 'rebirth' & each 'birth' will bring suffering. In his first words, the Buddha said:

153. Through many a birth in samsara have I wandered in vain, seeking the builder of this house. Repeated birth is indeed
suffering!
154. O house-builder, you are seen! You will not build this house again. For your rafters are broken and your ridgepole shattered. My
mind has reached the Unconditioned; I have attained the destruction of
craving

user4928: While this answer might be controversial on this site I myself have struggled with this question for a long time. This is my perspective, nothing more. 
The answer is no, currently, there is not a proof of karma or reincarnation that I have found to be convincing. 
However, the inverse is also true... there is not a proof that eliminates the possibility of karma or reincarnation that I have found to be convincing. 
The conclusion I came to was that the timetables involved of lifetimes of rebirth made it impossible to set up an experiment that proved the issue one way or another. Believe me, I tried, for ~3 years I made myself the experiment. It was an existential adventure I do not regret. 
Now it is said that some people after a certain point in the path remember all their past lives, and to them, that would be a personal proof. But to me it is anecdotal, and I could not accept it as proof unless I myself experienced it. Even if I experienced it myself, I would not consider it a proof for other people for the same reasons.

See my answer here. It explains how Buddhism is a practical religion and not based on blind belief.

I'm interested in knowing the proofs of Karma theory & rebirth presented by Buddhism.

The only proof obtainable is by practicing insight meditation thereby seeing with your own eyes how phenomena arise and cease and how they can cause new phenomena to arise.

user7309: Buddhism differs from others in that rebirth is not a transmigration of a Soul, nor of any specific entity. It is more of a statement that perceived experience being subject to conditions - finding itself empty of any and all self referential properties - cannot logically be seen to either have a concrete beginning nor a concrete ending, whilst the conditions for the arising of said experience are present.
When the notion of an Essential, Independent and Unchanging Atman/Soul is taken at its word, then at birth and death, that Soul must either appear from somewhere, or disappear somewhere, respectively, as Essentialist religions infer. 
The Buddha's aim was to show that what is directly perceived - impermanence and non-self - does not allow for termination of the conditioned (as that would be a process with a permanent conclusion), nor does it allow for some unconditioned and unexperiancable entity flirting off to invade somewhere else, as that is not directly perceivable by entities that depend on conditions for their perception.. 
The point is that there is no duality of 'cessation of the conditional'+'non-cessation of the non-conditional'. There is simply the continuation of conditionality. Ending the process of rebirth is the act of removing whatever conditions make up the necessary support for some conditionally-defined object: there is no 'rebirth' for my desire to drink, because I have removed the necessary conditions for this conditioned entity called 'me' to lunge for booze - the condition removed is craving for beer. This craving is removed volitionaly - volition being the arbiter of Kamma and its fruit: empty of volition? Empty of Kamma and hence empty of rebirth. 
(I will be the first to say that this logic works a lot easier for 'beer' than for the entity labeled 'me'. But there is no concrete dividing line between the two concepts - as for any two concepts - given that true Independence is not possible within conditionality, so the beer example should be a decent starting point!)

user8044: There are many, especially in the western world, who’d rather have Buddhism without rebirth because they do not believe in rebirth. They are turned off by the concept of rebirth because most major religions are based on three levels of existence: This life, and one of two eternal stages of life thereafter.  It is either heaven or hell for eternity based on what one does in this life. Also they just cannot fathom the possibility of being reborn as an animal
The concept of rebirth is a paradigm-changing concept, and one needs to put aside all preconceived notions to understand this core message.  The reason rebirth is a core message is that this life is only but an insignificant time in the cycle of rebirths that we have been on from eternity. 
The sense of urgency to follow diligently in this Dhamma Path comes when one realizes suffering in many of the lower realms of existence is much worse than that in the human or even the animal realm. When one gets more and more into Dhamma, one realizes that rebirth is an inseparable part of being a Buddhist in the truest sense.
The Pali word for Buddhist means “a person trying the stop the rebirth process” (“Bhava+uddha” = Bhauddha). One meaning of Buddha Dhamma is “path or method of removing bhava and thus stopping the rebirth process”. Buddha means, “one who has removed bhava (and attained Nibbana)”.
For evidence of Rebirth one can refer to the research done by the late Professor Ian Stevenson at the University of Virginia. He has done over 20 years of research on the authenticity of rebirth accounts. Also refer to Professor Jim Tucker’s books about rebirth. A good book is “Twenty Cases Suggestive of Reincarnation” by Ian Stevenson.
There are hundreds of youtube videos on rebirth stories and also many on child prodigies and hypnosis-based curing of certain ailments.

We can see various levels of human happiness/suffering around us. We see some people live with relatively higher levels of health, wealth, and happiness, while others live in poverty, ill-health, and misery. This in itself is proof of Kamma.
A child may die prematurely, or someone may get brutally murdered. What could be the underlying causes for such misfortune. Nothing happens in this world without a reason or without a cause. 
Does it just happens that X is born healthy and wealthy, Y is born healthy but poor, and Z is born handicapped and poor? There must be REASONS why X, Y, and Z are born that way. Many times a person born rich can become poor, and vice versa. Or a person in good health can die suddenly in an accident or by a heart attack. The laws of kammā can explain all the above.
