Valued Upasaka, Upasika,
Valued Team here and for awakening seeking readers,
whether young or old, lay person or ordained, since child one would be trained in generosity after having made merits, may it be just a recitation, veneration, after a giving, after taking precepts, after a meditation session, after having listened to Dhamma.
In traditional countries there are many deep and beautiful verses used an known. Here some may know a traditional recitation as sample: Dedication of Merit

Do you know or even practice a certain Verse and feel inspired sharing it?
Do you know good and nice sources (not commercial but dedicated as Dana) of valuable Verses in various languages?

Feel inspired to share you ways and possessions.
If inspired to even share an audio of your recitation, feel invited to do such here: Rejoice with others & sharing merits pattanumodāna & pattidāna. You can link it into here and no need to take uninvited space or contracts anywhere.

user6994: In Tibetan monasteries, we recite part of Shantideva's Bodhisattvacharyavatara (Bodhisattva Deeds) Chapter 10. It has 58 verses. The whole chapter relates to dedication and the practice of the perfection of generosity. It is really inspiring. To quote 8 verses:

May no living creature suffer,
  Commit evil or ever fall ill.
  May no one be afraid or belittled,
  With a mind weighed down by depression.
May the blind see forms
  And the deaf hear sounds.
  May those whose bodies are worn with toil
  Be restored on finding repose.
May the naked find clothing,
  The hungry find food.
  May the thirsty find water
  And delicious drinks.
May the poor find wealth,
  Those weak with sorrow find joy.
  May the forlorn find hope,
  Constant happiness and prosperity.
May there be timely rains
  And bountiful harvests.
  May all medicines be effective
  And wholesome prayers bear fruit.
May all who are sick and ill
  Quickly be freed from their ailments.
  Whatever diseases there are in the world,
  May they never occur again.
May the frightened cease to be afraid
  And those bound be freed.
  May the powerless find power
  And may people think of benefiting each other.
For as long as space remains,
  For as long as sentient beings remain,
  Until then, may I too remain,
  To dispel the misery of the world.

The main difference between dedication and aspirational prayers is that, when we dedicate, we offer a substance such as our merits. In the practice of "exchanging oneself with others", we offer our happiness and its causes to sentient beings. When we dedicate, we intend for our merits to ripen in ways beneficial for others. It is slightly different. We usually say that dedicating one's merits (accumulated through cultivating compassion, love, etc) is like saving one's money. Merits saved will not go to waste. It is better that the merits ripen as pleasant feeling in dependence on studying the teachings of the Buddha than in dependence on eating ice creams.
Another verse of Shantideva goes:

May all beings everywhere
  Plagued with sufferings of body and mind
  Obtain an ocean of happiness and joy
  By virtue of my merits.


user701: 
For sharing merits with the departed relatives we use,

Pali verse: ldam me ñatinam hotu sukhita hontu natayo [3 times]
Meaning: 
  Let this merit be received by my relatives, and may they be happy [3 times] 

For sharing merits with the devas and nagas we use,  

Pali verse:
Akasattha ca bhummattha
  Deva naga mahiddhika puññam tam  anumoditva
  Ciram rakkhantu sambuddha-sasanam, ciram rakkhantu sambuddha desanam, ciram rakkhantu mam param
Meaning: May all the devas and the powerful nagas inhabiting space and earth, enjoy these accumulated merits and protect long the religion, the teaching and myself

For sharing merits with all beings we use,  

Pali verse:
Ettavata ca amhehi sambhatam puññasampadam sabbe deva anumodantu, sabbe bhuta anumodantu, sabbe satta anumodantu
  sabba sampatti siddhiya
Meaning: May all the devas, the spirits and all beings share the merits we have accumulated and thus accomplish their happiness.



user11074: There are probably as many answers to this question as there are Buddhists, but as you ask the question to all, I thought maybe I can offer something about the rule, rather than the form.
There are several textual sources regarding what is appropriate for dedication - in general one may dedicate ones' actions any way one may wish, but then the behaviour does not lead to liberation, and is therefore not Dharma activity, unless the dedication is in line with Dharma activity.  
These are the four ways of dedication that are in accordance with Dharma activity, as I have been taught from within the Himalayan tradition:

Dedication towards one's own liberation and enlightenment.
Dedication towards the liberation and enlightenment of all beings.
Dedication towards the longevity of Buddha's words. 
Dedication towards the longevity of the Sangha and one's Dharma teachers.

Of these four, the best is the first because it involves taking personal responsibility for the Buddha Dharma through the greatest means possible.
