I have some GPIOs I'm using as outputs with code like this:

J2[21].function(PINJ2_21_GPIO);
J2[21] = 1;

I'd like to be able to read the state of these pins, but if I do something like i=J2[21] they change to inputs. I'm using shadow registers to get around this, but I'd like to know if there's an easy way to read the current state of a pin set as an output without switching it to an input?

Not really,
You can read the commanded state...
(you did not say what platform and if you running 3.X or 2.X )

J2[21].readBack(); Should give you the current state without changin the drive/direction setting...
