I don't use LNCS myself, but since it ships as a style file rather
than a class file, I think you should be able to start a new document
in the default article class in LyX and then add '\usepackage{lncs}'
to the preamble (Document -> Settings... -> LaTeX Preamble). If there
are any special features (rather than just changes to various style
parameters), you'll either need to use ERT (plain LaTeX) to invoke
them (in which case they may not look right in the GUI, even though
they display correctly in the final output) or else cobble together
your own layout file (section 5.2 of the Customization manual).
If it's a style file, then you can also copy article.layout to
lcns.layout and do this:
# \DeclareLaTeXClass[article]{article (LNCS)}
Then add whatever you like.
