Play your basic chords and add flat 3s to 3s hammer ons and pull offs. Add 7ths. Throw in a 4,#4,5 run here and there. Bend flat 3s to 3 too.
Slide up or down from notes in one chord to notes in the same chord higher or lower on the neck. It is a place to start. I don't use pentatonic scales myself so I can't help you there.
