Workouts with Bodyweight, Hex Bar, Kettlebells, and Power Tower?

Let me start off by saying I know T-Nation is a mostly meat eater, get after it in the gym, power lifting in the cave kinda place and I LOVE THAT. Well used to. I lifted for 4 years straight, 5 days a week. I got pretty yoked, just to lose it. Unfortunately, I haven’t found myself in a gym for 4 years. Almost the amount of time I have been out of the Marine Corps. I went from 6’2 240 at 12-14% bf to 6’2 250 probably 30-35% bf. I looked at myself in the mirror today while getting in the shower and thought “What the fuck have you let yourself become, man boobs.” I haven’t got a compliment about my physique in years. I just had my first kid and t I’ll be damned if she has to look at her 250lb piece of chewed up bubble gum father growing up. All my house allows me the space to have is a hex bar, some kettle bells, and a power tower. Can somebody, anybody help me get back to being in better shape than I was with a good workout routine with the limited amount of equipment given. I like the thought of being able to do a ton of push ups, pull ups and dips. I don’t need to be 240 and fairly lean, anymore. I’d be okay with just being lean and cut up. HELP. Any advice is greatly appreciated. Honestly.
