In a medium saucepan heat oil over medium-low heat. Add garlic, cook a few seconds then stir in paprika and pureed tomatoes. Add sugar, basil, oregano, bay leaf salt and pepper. Bring to a simmer, lower heat, and cover. Cook for about 10 minutes or until it has the right consistency for spreading on your pizza. When done, remove from heat and let cool slightly before using on your pizza.
Preheat the oven to 400°F (200°C). Punch the dough down, knead, split in 2 pieces. Shape each piece into a ball, then roll out into a circle about 12 inches (30 cm) in diameter. Place it in greased pizza pan and punch some holes in the dough with a fork.
Spread tomato sauce over the dough and sprinkle with oregano and basil. Spread the mushrooms, olives and corn kernels over dough and sprinkle mozzarella on top.
Place in the preheated oven, switch for heat coming from down and bake for 15-20 minutes, until the cheese has melted and edges of crust are golden brown.
