In formulas, you can just enter raw LaTeX if you like. E.g., you can
type "\hello{hi}", and that is precisely what you will see. If you had
in your preamble:
\newcommand\hello[1]{2^{#1}}
Then you'd get the output you expect.
Note that you do need to be careful about whether the brackets are
escaped, i.e., whether the LaTeX is: {, or \{. LyX displays "argument
brackets" in red, and "delimiter brackets" in blue. To get the former,
you type \{, ironically enough, though you will get them automatically
immediately after a command.
