Without using AAS it's very hard to loose significant amounts of fat and gain significant amounts of muscle - its bloody hard if you are unless you're blessed with an ideal metabolism.
My advice would be initially to aim to loose the fat while maintaining as much muscle as you can, as tall says there’re several approaches, to my mind the simplest is medium low carbs with high protein and low fat, split over seven meals per day 3 from protein / mrp drinks and four from solid food.
You need a good quality protein drink and I would also suggest l glutamine as its an excellent anti catabolic, I take a tea spoon with each liquid meal.
Once you have your fat levels something like start carb cycling which means a high carb day every few days.
Tall is right training for strength and training for maximum muscle growth are very different and while training for one will promote the other to some extent but nothing like training specifically for that end result– decide what you want to achieve and then construct your training plan and diet to achieve that.
If you have a read of my journal there’s quite a bit about my bulking and cutting diets, if you like the look of it and have any specific questions ask away
