Hi,
I'm in my first year too. I've just presented some of my literature review at a conference (last week). How I went about it was to choose an issue in the literature and focus the paper around that. I then made sure I had covered the relevant literature for what I would be talking about.
I basically gave a critical view of a the literature, highlighting the underlying assumptions and potential consequences of a particular change happening in my research area (social science). I wasn't critical about the change, but just highlighted some issues with it that may need addressing. It seemed to go down well. I wasn't saying "this is what the literature says" but more "this is the current situation, these are some concerns I have with it that should be considered"
I was worried it may be controversial, but it was well received!!!
Good luck - I only had 15 minutes and don't think I could have physically covered my whole literature area in the time! I also didn't touch on any PhD theses.
