I'm totally new to QGIS so I'm not even sure this is possible.

I've created a bunch of polygons within QGIS and they look just like I want them (color, transparency, etc.).

What I'd like to do now is to export this somehow so that this same formatting is visible in a Google Map I'm creating as a layer. Is this possible? What format do I export?

I've tried exporting as geoJSON, but what appeared in Google Maps was not formatted. The boundaries of the polygons were there, but no colors, etc.

    afaik this won't work with geojson but you might want to check the KML questions for pointers.

The idea is to set the style in the script. This makes the GeoJSON more flexible than KML where this is done in the file itself. Use: map.data.setStyle and the fillColor option, like it is described in the documentation. You can even give each polygon a separate style based on your json data.
