Drain and rinse the jackfruit, then use a fork to shred the pieces until they resemble the texture of pulled meat.
Shred the seitan into thin strips or small crumbles to match the jackfruit consistency.
In a non-stick skillet over medium heat, combine the jackfruit, seitan, adobo sauce, garlic powder, onion powder, smoked paprika, sea salt, and black pepper.
Sauté the mixture for 8-10 minutes, stirring occasionally, until the edges are slightly crispy and the sauce has thickened.
While the filling cooks, place the avocado, nutritional yeast, lime juice, and water in a small blender or food processor and blend until completely smooth.
Warm the corn tortillas in a dry pan over medium-high heat for 30 seconds per side until soft and pliable.
Assemble the tacos by dividing the jackfruit and seitan mixture between the tortillas, topping each with a dollop of avocado crema and fresh cilantro.
