Can anyone make me an MMA training routine for the gym?
Bas Rutten sells a series of books that address this that I highly recommend. As far as what I would offer you to start you will need conditioned muscles as well as wind so hit the gym three times a week. Alternate pushing and pulling set muscles, example being bicep/triceps. Do the most weight you can do 25 times, when you can do three sets of 25 up the weight. Hit every muscle group and take little to no rest in between sets. This will build strength as well as condition your muscles. It is the huge Oxygen eating muscles that cause a lot of fighters, especially in the beginning, to gas out quick. A guy may be stronger than you because he does a pure power routine and runs, but if you can use your technique to weather the storm for a minute or two his strength will fizzle fast.
