Look up Steve Vai's 30-hour workout on Google and manipulate it to suit your needs. You don't need to practive 10 hours every day; that's more than a standard full time job!

Technique

Chords/Rhythm
Scales/Arpeggios

Music Reading
Ear Training

Repertoire
Improvisation

Music Theory

I do at least one category out of each little block everyday and am getting great results from it. Not to mention I also log and keep a diary of what I did each day.

You don't have to include anything in it. What you practice should be suited to your musical goals. If you just wanna shred your ass off then obviously you want to do heaps of technique stuff, where as if you want to write songs and improvise than theory and ear training are also important. Once you know your goals you can figure out what you need to work on to improve your skills and accomplish those goals, and then make a balanced practice routine working on the skills you want to improve.
