Preheat oven to 400°F (200°C); line baking sheet with parchment or silicone mat.
Pat vegan “chicken” dry; season with salt and pepper.
Pour flour into a shallow bowl; whisk plant-based milk in another.
Mix vegan parmesan, garlic powder, smoked paprika, black pepper, and panko in a third bowl.
Dredge “chicken” in flour, then milk, then parmesan-panko mixture; press lightly for coating.
Place coated “chicken” on prepared baking sheet; spray lightly with oil for crispiness.
Bake 25 minutes until golden and firm; flip halfway for even crust.
Serve immediately with veggies, salad, or pasta; drizzle with extra vegan butter if desired.
