I was training on Local Control; finishing a departure push. Aircraft X called ready for departure. A twin engine aircraft departed for touch and go's runway heading requesting single engine operations for training. I cleared the aircraft for takeoff on a heading of 080; the Local approved turn for a VFR aircraft. The aircraft departed and I told them to contact Departure Control. When the aircraft ID showed on the radar display it was on an IFR not VFR tag. The aircraft was already in the turn below the MVA of 4;100 ft. This occurrence can be avoided by better flight strip management and a better scan of all resources available in the tower.
Developmental Tower Controller reported mistaking an IFR aircraft for VFR traffic; resulting in vectoring the aircraft below the MVA.
