Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Pat the extra-firm tofu dry with a clean towel to remove excess moisture and cut it into 1/2-inch cubes.
In a large mixing bowl, combine the cooked chickpeas, tofu cubes, broccoli florets, and sliced red bell pepper.
Drizzle the mixture with olive oil and sprinkle with garlic powder, smoked paprika, sea salt, and black pepper, tossing until every piece is evenly coated.
Spread the ingredients in a single layer on the prepared baking sheet, ensuring they are not overcrowded to allow for proper roasting.
Roast for 25 to 30 minutes, tossing the mixture halfway through, until the vegetables are tender and the chickpeas and tofu are slightly golden.
Remove the tray from the oven and immediately sprinkle with nutritional yeast and hemp seeds while the food is still hot so they adhere well.
Transfer the roasted mixture into a bowl and serve immediately while warm and fragrant.
