I can't advise you about technique, as mine is not great. I practice by playing tunes and trying to find new ways to improvise on those tunes. If I try to play a particular sequence of notes and find that my fingers won't obey I practice that sequence.
There are undoubtedly universal methods of practicing for playing jazz, and others here who can advise you. For me, practice is a practical matter of preparing for my next gig or adding to my repertoire, so I'm guided by the requirements of the tunes I'm playing.
