However, depending on the context, you might consider these words as close as you can get to a homophone:
* Hall: This is the closest in sound, but it refers to a corridor or a large room.
* Haw: This word can sound similar depending on the dialect, but it means "to stop or turn an animal" or is an exclamation used to get an animal's attention.
Ultimately, the best way to convey the meaning of "haul" is to use the word itself.
