Using \renewenvironment didn't work (LyX still treats it as an eqnarray and adds
an extra &).
Sorry my fault, this is of course not possible because align has 2 columns,
eqnarray 3 columns.
So the easiest way is to define a keyboard shortcut that inserts an align equation. How to define
such a shortcut is explained in the Customization manual. (The next major LyX release has a dilaog
where you can define them much more easier.)
For existing formulas, use the menu Edit -> Math -> Change formula type
(shortcut Alt-m t a).
