Preheat the grill on high for 5-10 minutes. Allow store-bought dough to rise at room temperature for 20 minutes.
Punch the dough to form a crevice, then drizzle the olive oil, garlic powder, onion powder and oregano in the crevice. Massage the olive oil and spices into dough, then stretch and roll out the dough into a circular shape.
Place the dough on the grill. Brush the top of the dough with a thin layer of olive oil, then close the grill and cook for about 2 minutes. The dough should get some grill marks on it, but should not look burnt.
Use tongs to flip the dough, the brush more olive oil on top. Spread a thin layer of the sauce, then add the corn, tomato slices, mozzarella and sprinkle paprika. Be careful not to overload the pizza so it cooks evenly.
Close the grill and cook for 3 to 5 minutes, until the cheese has melted and the bottom of the crust is lightly charred.
Use tongs to remove the pizza from the grill. Let cool for a few minutes to cool and then slice.
