I think a workout based around large compound exercises such as squats, bench presses, deadlifts etc will be a good starting point in a strength training routine for MMA. I would suggest adding some exercises that will help to improve your explosive power. Exercises where you can shift a lot of weight quickly such as snatchs, clean and presses, push presses. Use a heavy medicine ball and introduce some overhead slams and rotational throws into your programme as well as some plyometrics. For example try doing a set of plyometric step jumps straight after a heavy set of squats to really burn the legs. Hope this helps.
