From a diet perspective, try to get .7-1g of protein/1lb of lean body mass and start shooting starch like there's no tomorrow. Some would recommend more protein but from what I've witnessed/experienced, getting as much protein as your body can process efficiently followed by making up the rest of the calories in starch and fat is a smarter way since much of the excess protein will be converted to glucose via gluconeogenesis anyways. What you're looking for is a calorie surplus with as healthy food choices as possible that do not mess with your health markers. I think the way I've outlined is a smart way to go about it, nutritionally.
As far as strength training goes, lift 2-3 times a week VERY heavy with low reps(6-10) and 3-4 sets per exercise. Try to get at least 2 exercises in per bodypart. We're aiming for hypertrophy, which can have similar goals to strength increases but more volume can be applied for maximal muscle growth.
Edit: Deadlifts and Squats should be at the centerpiece of your strength training since they do more than any other exercises to shock the CNS and trigger release of growth hormones. Also, keep the movements to simple, compound movements. Leave the cutesy stuff to the bodybuilding mags.
