I'm working on a Liferay 6 project, and part of the project is to create a new layout template to be used for the entire site as the default. Liferay's own wiki is very sparse on documentation about layout templates, and I haven't had better luck with Google searches or even here on SO.
I did find one article ( Liferay - Layout for each pages ) that sort of answers the question, but it seems like it might be overkill. In that question, the goal was to change the template based on the page, so the answer was to create a Hook and use that to set the template on the fly as needed. Here, I just want to have this custom template be the default for all pages, all the time, which is why I think the answer to that other question might be more than is really needed.
If anyone has the answer to this puzzler, please let me know. Thanks!

OK, I've figured out my confusion. Liferay has two types of layout templates -- templates that are part of a theme, which is one type of Liferay project, as well as actual layout template projects themselves.

I hope this helps some other people trying to figure this out!
