Copy and paste as text in your LyX document everything between (and including)
\begin{align*} and \end{align*}. Now select everything you pasted and then
hit Ctrl-m.
In LyX you get the align* environment through Insert>Math>AMS align Environment
and you add more row/columns through Edit>Row&Columns.
