I found the recipe at the office.
1 1/2 cup Soy Sauce
1/2 cup Worcestershire Sauce
1 cup light brown sugar
2 teaspoons liquid smoke
1/2 teaspoon garlic salt
1 teaspoon onion powder
Mix the marinade to dissolve the sugar and other seasonings.
I have made the jerky from beef and turkey. You could use other meat, but I haven't tried. Cut the meat in strips WITH the grain. The strips should be less than 1/4 inch thick.
Soak the meat in the marinade overnight. Put the meat in the oven or dehydrator and set the temperature to 180 or so. It might take 10 hours to get the right consistency. Your preference will determine how dry you want the jerky. Red meats contain a good amount of fat, so they remain soft, even when a significant amount of water is gone.
