Preheat oven to 400°F and line a large baking sheet with parchment paper.
Press the tofu with a clean towel to remove excess moisture, then cut into 1/2-inch cubes.
In a large bowl, toss the tofu cubes, chickpeas, and broccoli florets with olive oil, garlic powder, sea salt, and black pepper.
Spread the mixture in a single layer on the prepared baking sheet.
Roast for 25-30 minutes, tossing halfway through, until the tofu is golden and the chickpeas are slightly crisp.
While roasting, ensure the quinoa is warm and ready for assembly.
Transfer the roasted vegetables and tofu to a bowl over the quinoa base.
Sprinkle with nutritional yeast and hemp seeds for a protein boost, then finish with a squeeze of fresh lemon juice.
