I'm beginning to develop a style/FLAVA on the keyboard. What I've done so far is listen to songs specifically for the piano/keyboard part. I also have been playing peices that are from different songs with excellent piano parts. Chords that I liked, I made my own songs off of, used those kinds of chords. I also Played around with the notes to different kinds of songs, trying to incorporate those chords into the song I was playing. I afterwards started experimenting with runs using the same technique. Its not as complicated as it sounds. I hope that helps.
