Rinse the canned jackfruit thoroughly and pat dry. Use your hands or a fork to shred the jackfruit and crumble the seitan into small pieces.
Heat the olive oil in a non-stick skillet over medium heat. Add the shredded jackfruit and seitan, sautéing for 5-7 minutes until the edges become slightly golden and crispy.
Stir in the garlic powder, onion powder, cumin, sea salt, and black pepper. Add the adobo sauce and water, stirring to coat the mixture evenly.
Reduce heat to low, cover the skillet, and simmer for 5 minutes until the liquid is absorbed and the flavors have melded.
In a small bowl, mash the avocado with the lime juice and half of the chopped cilantro until a smooth, creamy consistency is reached.
Warm the corn tortillas in a dry pan or over an open gas flame for 30 seconds per side until soft and slightly charred.
Divide the adobo jackfruit and seitan mixture between the tortillas. Top each taco with a dollop of avocado crema and the remaining fresh cilantro.
