you want your army composition vs terran to be ling muta (unless he mechs) so build 2 more queens if you suspect him going banshees.
as a rule you should always make 3 queens (1 for each hatch and 1 to spread creep) so just make 1 more for the banshee.
you should also hatch first before pool vs terran
muta counter vikings alot better than corrupotors so dont make corrputors
use your queens to stall till you get your mutas and his banshees will be in trouble.
