1. Type it as normal text in your paragraph.
2. Mark it and press Ctrl-M to convert to Math
3. Repeat (mark and Ctrl-M) to convert to Text-in-Math.
(Tested with LyX 1.6.0 on Debian. AFAIK, this worked also in 1.5.
In earlier Versions, the trick is to drag and drop the LaTeX-math expression
with the mouse in a math box.)
BTW: 1.6.0 on Debian also allows entering spaces in Text-in-Math and
you leaves this mode with right arrow. Maybe upgrading to 1.5.7 helps
(if 1.6.0 is not an option).
