There is no automatic translation from LaTeX .cls files to LyX .layout 
document classes definition files. But it is understandable that you 
thought this is how it works since this is not transparent from the 
Document Class user interface. Maybe that could be improved by showing 
the .layout file names somewhere...

Anyway, in order to make use of a .cls file in LyX, you would need to 
create a custom .layout file in your local "layouts" folder. You could 
start with a copy of a .layout file corresponding to a class that is 
similar to the one you are using, e.g. article.layout if it is an 
article style class.

There are more explanations in the Customization Help file. It is a bit 
of a hard read though. But I am sure people on the list are happy to 
support you a bit.

Best,
