I declared my first ever emergency yesterday after encountering
unexpected ice. I only accumulated about 1/4 inch so it wasn't that
big a deal, but I lost my engine gauges (I fly an SR22), which
included my OAT, so I went ahead and declared so I could descend
below the MEA to shed the ice before anything else went wrong. About
a minute after declaring I broke out into VMC.

My question is: is there any FAA paperwork I need to do? I already
filed an ASRS form.


You have to notify ATC as soon as possible, I assume you did that. After
the fact you're required to submit a report if the Administrator requests
one, that's unlikely.
