Just do 3 compound exercises per day. One pull, one push, and one leg exercise. You can do some auxiliary exercises after that if you're not too tired.
Alternate horizontal (chest presses, db, bb, flat, incline...) and vertical (overhead presses, dips) pushes.
Alternate horizontal (seated rows, chest-supported rows, bent-over rows) and vertical (chin-ups, pull-ups, power cleans) pulls.
Alternate quad dominant (front squats, reg squats, box squats) and hip dominant leg exercises (sumo deadlifts, reg deadlifts, good mornings, romanian deadlifts). Also throw some unilateral exercises (lunges, step-ups).
Rotate the order of the push/pull/legs exercises. I.e. one day start with push, next day with pull, and next day with legs.
Do 8x3 (8 sets of 3) one day, 4x8 next day, 5x6 next, 3x12 next, and start again. Or whatever other rep/sets tickle your fancy. Just make sure you do some low reps at some point during the week (for strength), and keep the total number of reps per exercise > 24 (for size).
All of this is very much the same as Chad's SOB program, although he alternates 1 day on / 1 day off. (And I'm sure there will be a lot more differences since I'm just a guy that lifts, not a coach.)
