Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Press the extra firm tofu with a heavy object for 10 minutes to remove excess moisture, then cut into 1/2-inch uniform cubes.
Rinse and thoroughly pat the chickpeas dry with a kitchen towel to ensure they become crispy during roasting.
In a large mixing bowl, combine the tofu cubes, chickpeas, and broccoli florets with olive oil, sea salt, black pepper, and garlic powder.
Spread the mixture in a single layer on the prepared baking sheet and roast for 25 to 30 minutes, tossing halfway through, until the tofu is firm and chickpeas are golden.
While the vegetables roast, steam the shelled edamame in a small amount of water until tender, then drain.
In a small bowl, whisk together the fresh lemon juice and tamari to create a bright, savory dressing.
Assemble the Buddha bowl by placing the roasted tofu, chickpeas, and broccoli alongside the steamed edamame.
Drizzle the lemon-tamari dressing over the top and finish with a generous sprinkle of nutritional yeast for a boost of umami flavor.
