Prepare Tofu: Drain and press the tofu to remove excess water. Cut into small cubes.
Marinate Tofu: In a bowl, mix the tofu cubes with soy sauce, ensuring they are evenly coated. Let them marinate for about 15 minutes.
Fry Tofu: In a large skillet or pan, heat the vegetable oil over medium-high heat. Add the marinated tofu cubes and fry them until they are crispy and golden brown on all sides. Remove the tofu from the skillet and set aside.
Sauté Aromatics: In the same skillet, add a bit more oil if necessary, and sauté the onions and garlic until they are soft and fragrant.
Add Peppers and Seasonings: Add the chopped green chilies and red bell pepper to the skillet. Cook for a few minutes until the peppers are soft.
Incorporate Rice: After the peppers are softened, add the cooked rice to the skillet. Stir well to combine with the aromatics and peppers. Cook until the rice is heated through and starts to get a bit crispy, stirring occasionally.
Combine with Tofu: Return the crispy tofu to the skillet. Stir in the lemon juice. Mix well. Season with salt and pepper.
Serve: Serve hot, garnished with chopped green onions. Accompany with calamansi or lime wedges.
