Converting wood joists to steel

[fiddlesticks]

I would like to know if there are any guides or tables that will allow you to convert 2x Douglas Fir joists to an equivalent rectangular steel tube.

There is no guide that I am aware of. I would imagine any structural engineer would simply run loading equations to calculate the required cross sectional moment required for the new material.

I forgot to mention that the USDA puts out a free handbook that is pretty good that includes a lot of engineering data on wood. That should be a big help for you.
