Hi, 

does anyone know of any tips for taking the thumbnail and preview images of models? 

I have some models I'd like to submit but I don't know how to get the lighting and transparency for the previews. I'm working in Blender if that helps.

Any help would be appreciated!

To make the background transparent, turn on Properties Editor > Render Tab > Film > Transparent, see here.

Another thing you should consider is changing the color management to "Standard" from the default "Filmic", see here. Filmic produces noticeably dark colors that are rarely appropriate for game models IMO.
