I'm not an expert, but I think he should start with a basic program like:
Day 1
squats
bench
row
Day 2
deadlift
overhead press
pull-downs
Start with lighter weights (form is more important than weights because his body isn't going to know how to move properly under load and you need to teach it).
Do them on Monday/Wednesday/Friday, 2-3 sets of 8-12 reps (3-5 reps on deadlift), just focus on adding reps and learning the form. Once you've got the form down, he can start gong heavy and working out in the 3-6 rep range. He can also start adding an assistance exercise or two.
