The two things that you should probably do right away when starting with frogs:
1. Use braid. There is little to no stretch in the line which allows you to impart a good amount of force on the hook points.
2. Bend the hooks up slightly. You don't want to go too much, since it'll hang up more often. Just enough to bring the hook points off the rubber.
Beyond that, make sure that you aren't jumping the gun on the hookset. Let the fish turn so there's a better chance of the hook grabbing hold of the mouth. You can also trim the rubber legs to help with short strikes. You can also add weight to one side of the frog, or cut one leg shorter to allow it to walk like a Zara Spook. If you're fishing it above submerged vegetation, and there isn't a chance of getting snagged you could add trailer hooks or something like this:
