I know that Hawking radiation has never been detected, but if we were to attempt to detect it, what would we expect it to look like?

We would expect it to look like thermal radiation, the same spectrum that comes from any hot thing (minus the spectral absorption lines). The temperature that the spectrum corresponds is inversely proportional to the mass of the black hole, and anything stellar mass would be extremely cold.
