Put boiling water, oil, liquid smoke, and salt into a mixing bowl.
Mix well until salt dissolves.
Add TVP and stir well until evenly coated.
Let it sit for about a minute until it soaks up all the liquid.
Pour onto a cookie sheet and spread it thin.
Bake for about 30 minutes until dried out and crisp. (Check on them and give them a shake about every 10 minutes to help them dry evenly).
Notes
Keep them in an airtight container in the fridge, they will last a few weeks.
If you want them to be lower in sodium, simply reduce the salt.
Make sure to shake the cookie sheet or give a little stir a few times while baking to make sure they cook evenly.
You can also substitute Butler soy crumbles instead of TVP. These are very similar, but they are made with whole soy instead of soy flour.
If you taste them before they are done cooking, they will taste different than the finished product, so don't toss them out thinking that they are not done.
