The final submission process for a paper I've composed in LyX requires submission of a single .tex file. I've had some success toward that goal but I still have some major gaps towards getting that all ironed out.
There are a couple of related questions on this site, which makes me wonder whether I should submit an "Export as Flat" feature request to the LyX folks, but this journal's requirements may be unusual; I don't really know. They can be found at 1.
So, I dug into the .tmp files that LyX creates (and I'm on Mac, so that's a little tricky to start with) and found some of what I wanted: a .tex file with all of the file names for figures collapsed to remove all directories, all of the actual figure files, and a .bbl file.
However, my first problem is that it's been so long since I've tried to use LaTeX directly, I'm at a loss of how to finish it all off.
One complication being that the TeX utils don't even seem to be on my path at the command prompt. I thought that I'd be able to at least find the path to the LaTeX executable thingy in "Preferences", where it has the path for things like dvips, but alas I'm still stuck.
I'm sure that the .bbl file gets turned into .tex and some point, but I haven't been able to find such a thing among the .tmp files produced by LyX, or figure out/remember how that part of it works.
And I feel like to need to be able to do the tex2dvi thing on the files once I've got them ready for submission, so that I can make sure it all still works like it did in LyX to produce the PDF.
And I thought that I would see the commands used in the .log file. But in there I could only see the output from those commands, and not the actual commands used (maybe that should be a LyX feature request, too).
Anyway, any insight that a LyX veteran could provide would be greatly appreciated.

From within LyX File->Export->as LaTeX. It makes sense to export it into the current directory of the LyX file. Then run the file from the terminal window:
This is what LyX does for you if running the LyX doc. That should create the files .pdf and also .bbl
