To make the tofu, first stir together the soy sauce, maple syrup, and smoked paprika in a small bowl.
Coat the bottom of a medium nonstick skillet with the oil and place it over medium heat. Give the oil a minute to heat up, then add the tofu cubes in a single layer. Cook the tofu for about 8 minutes, flipping the pieces once or twice, until they're golden brown.
Pour the sauce over the tofu and toss it a few times with a spatula to coat it with the sauce. Cook the tofu for another minute or two, until the sauce dries up. Transfer the tofu to a plate.
Place one of the collard leaves on a work surface with the veiny side up. Use a paring knife to trim the stem, then carefully take your knife and shave the portion of the stem that protrudes from the top of the leaf. Try to shave it down as close to the leaf as you can without cutting a hole in the leaf (Note 2).
Spread a quarter of the hummus about an inch from the bottom of the leaf, leaving a couple of inches on each side. Top the hummus with a quarter of the cabbage, shredded carrots, avocado slices, tofu, and chives. Sprinkle the fillings with salt and pepper.
Fold the stem side of the leaf over the fillings, tuck in the sides, and roll the fillings into the collard leaf.
Repeat the assembly process until all of your collard leaves and fillings have been used.
Serve.
