Hi,
I recommend going back to your teacher or finding a new teacher to re-invigorate your playing. I also recommend studying Jazz piano and working on your improvisation skills and theory. This will supercharge your ability to play tasty leads. There are some great books out there, but I find you need the instruction to go along with the teaching material.
Good luck and I hope you take that advice.
