Anyone have a good set of equations or example of how to do this

The fastest speed through the air mass will give the fastest speed

So add 0xW for a headwind and subtract 0xW for a tailwind.

I think Tim means STF for final glide where you are flying in
reference to the ground, not the airmass. John Cochrane's analysis
shows that you have different lift strength targets for upwind/
downwind turnpoints as well, though I don't know if this extends to
STF. John?

I have the final glide formulae in a spreadsheet, including effects of
wind and wing loading, if you are interested.
