I read somewhere that molasses and vinager is a good soy sauce sub. I'll see if I can figure out where I read it.
Here it is. From

For a soy sauce sub I use a dab of molasses in a little broth with a splash of balsamic vinegar, and Worcestershire. I might add some sea salt or red pepper spice.
but doesn't Worchestershire have soy in it?
