Place the roast in the freezer for 30-45 minutes to make slicing it easier. Once chilled, remove for the freezer and slice as thinly as possible against the grain. Cut the slices into strips if desired and place the steak in a large zip-top food storage bag.
In a medium mixing bowl, whisk together the soy sauce, brown sugar, Worcestershire sauce, black pepper, onion powder, garlic powder, and smoked paprika.
Pour the soy sauce marinade over the meat and allow to marinate in the fridge for at least 30 minutes. (I like to place the bag in a dish, just in case there are any leaks.)
Preheat the oven to 180 degrees F. Line two baking sheets with foil and put a wire rack over the foil on each sheet.
Arrange the beef pieces onto the racks so they do not touch, Place both trays in the oven and cook for 5 to 6 hours. Switch the lower and upper trays to the other rack after 3 hours.
Remove from the oven and allow to cool completely. Store in an airtight container.
