A couple ideas:
You may already be doing this, but as far as the running goes, if you try to incorporate a couple key types of runs, it may help: 1) long distance runs - once a week, try to run about 20%-40% farther than usual, keeping your pace slow and steady. Long runs are great fat-burners. 2) "Tempo" runs - once a week, try to run at a "comfortably hard" steady pace - stay at a pace that will feel quite difficult by the end of your run, but something you know you can maintain. It's faster than what you would run if you were trying to maintain a conversation, and you'll definitely feel worked at the end of it. Hope that makes sense. Tempo runs are really good for getting your body to a higher level of fitness, and you will definitely see results if you maintain these runs for the next 4-6 weeks.
Another idea for losing fat, which maybe is obvious, is to cut down on portion size. Not knowing exactly what your diet is, it is a little hard to make a recommendation here - but certainly you'll want to follow the basic principles of "eat real food (not processed stuff), not too much, mostly plants". Since you're trying to build muscle as well, make sure you have healthy sources of protein (like lean meats or fish, nuts, beans, greek yogurt, etc.).
I hope this helps and is not too obvious!
