I break my practice down into categories: 1) reading skills 2) technique 3) vocabulary 4) theory and 5) repertoire
To improve my reading I practice reading etudes, new pieces I am interested in, or Bach. I read slowly and will pause if need be to determine the best position and fingering. I may read the same piece playing in different positions as well, open position vs third position for example. I take note of where open strings work better vs fretting notes, and any odd left or right hand moves. I much prefer a clean score rather than a cluttered one with left and right hand finger notation. I like to work that out for myself to find what works best for me. I try to read at least a little bit every practice session, but some day more others less depending on my priorities at the moment.
I like to start my practice with about 30 minutes of technical exercises with metronome, similar to the ones you find in the Pumping Nylon book. I have made a few of my own exercises too that help with specific things I am trying to improve: picado, slurs, tremolo, arpeggio patterns, etc. Some days I do these exercises later in my practice session if I am more inspired to work on something else. I have about 10 etudes that I play through as well to help reinforce the technical exercises. I do notice my comfort, precision, and ease of play is much better after a brief technical workout.
Vocabulary work consists of chords, scales, and arpeggio studies in different keys and modes. I usually improvise or work with standard jazz chord progressions for this work. I work specifically on modes or keys that I feel need improvement. I play jazz standards and improvise as well as play classical guitar pieces, but I have found this work improves my fretboard knowledge and fluidity regardless of the style I am playing.
Theory usually consists of analysis of the pieces I am learning. I note the chords and chord progressions, mode and key, modulations, etc. It helps me better understand the piece and my memorization as well.
And repertoire consists of learning short and long term pieces. Some I learn rather quickly others are a long term project. I average working on around roughly 10 pieces per practice session. Short pieces I may play through completely, after working on any problem measures. Longer pieces I break down into sections.
All these categories are inter-relational and each helps to improve the others. I don't usually work on all five areas in one practice session, but by the end of the week I've usually covered them all.
Hope this helps!
