I'd suggest to use two documents: the actual beamer document that
contains all the text and a portmanteau beamer-article file that
basically simply \includes the beamer document. Then you can add
specific preamble code to either document.
See beamer-article.lyx in examples as a model.

If you use the textclass "Article (Beamer)" (not "Article"), the
beamerarticle package will be loaded and \mode is defined.
