I am currently an amateur boxer and the way I made my punches stronger is the fact that when I do a straight punch, left or right it doesn't really matter. The when you punch make it seem like you want to punch through your target. So when or if you are doing heavy bag work try to imagine that your are punching right through your target to get to the other side. And feet placement is very important as well. Use your legs, like an upward motion, the punch doesn't start from your arms but they start from your feet.
Punch straight through, guide your hand and arm into the arc wherever you want to direct your punch.
Punch with your knuckles, not your fist. If you punch with your fist, it'll hurt you more than your offender and the punch will not be as strong.
Try to punch slightly upwards, hurts SO bad.
And of course, to make your punches stronger, you have to strengthen yourself. Do abwork with mixes of cardio and muscular endurance and strength. If you want your punches and attacks powerful, you have to make yourself powerful too.
Learn how to punch using your legs, hips and shoulder rotation find a boxing trainer or look up video's of great punchers and how they use their legs, e.g. Mike Tyson throwing uppercuts or Joe Louis throwing combinations they are a couple of boxers that got as much power and leverage in their punches as possible.
