Welcome back!
When I come back from any layoff (never been off for more than a month or so), I just go 60 - 80% of my most recent work weights for 3 sets of 5, and go from there novice style, adding either 5 or 10 lbs per workout. Then again, I tend to be conservative in my approach, and have no plans to compete.
Since you have current maxes, may I suggest (start milk-loading now) something like:
Squat: 250 3x5
Bench: 185 3x5
Dead: 325 1x5
and try 10-15 pound progressions per workout.
Also; don't forget the overhead press.
