Preheat your oven to 400°F (204°C) to achieve crispy tofu.

Drain and pat dry the block of firm tofu, then slice into thin shavings about 1/8 inch thick.

In a bowl, whisk together vegetable broth, Bragg's Liquid Aminos, liquid smoke, smoked paprika, garlic powder, and cayenne pepper. Pour over tofu and let marinate for at least 10 minutes.

Lightly grease a sheet pan with olive oil or line with parchment paper.

Arrange marinated tofu slices in a single layer on the prepared pan, ensuring space between each slice.

Bake in the preheated oven for 30-35 minutes, flipping halfway through, until edges are golden and crispy.

Remove from oven, cool slightly, and serve or store in the fridge.
