You simply get on a split routine that has you hitting every body part every five to seven days with the appropriate exercises, volume, and exercise sequencing.
A split routine that allows you to bring up any weaknesses and pack on mass generally.
@willisrhood suggests a very good article, as are all of Clay Hyght's other articles on bare-bones bodybuilding training. Read all of his articles on here. As for nutrition and training, there are thousands of articles on this site for your needs. I strongly suggest you stay away from any articles by "strength" writers, personal trainers and strength coaches who solely train athletes or regular folks and so on. That is, if you want to look like a physique competitor or bodybuilder, pay attention to those who speak about bodybuilding or compete themselves.
Read CT's beginners' series on nutrition. That's enough to start with, as you are asking for a tall order for someone to write a detailed diet for you.
DUMP the powerlifting/"strength training" mindset. You WILL gain strength, maybe even A LOT of strength, on a properly implemented split routine, as if this is necessary to grow, and a bigger muscle is a stronger muscle, regardless of the style of training that was used to make the muscle bigger.
