Preheat your oven to 400°F (200°C) and line a large rimmed baking sheet with parchment paper.
Press the extra-firm tofu between paper towels to remove excess moisture and cut it into half-inch cubes.
Pat the cooked chickpeas very dry with a clean kitchen towel to ensure they become crispy in the oven.
In a large mixing bowl, combine the tofu, chickpeas, and broccoli florets with olive oil, tamari, garlic powder, salt, and pepper.
Spread the mixture in a single layer on the prepared baking sheet and roast for 25 to 30 minutes until the tofu is golden and the broccoli is tender.
In a small bowl, whisk together the nutritional yeast and lemon juice with one tablespoon of water until a smooth dressing forms.
Divide the roasted vegetable and protein mixture into bowls and drizzle the nutritional yeast dressing over the top before serving.
