The only thing I would do differently processing at night or be concerned about is making sure you don't accidentally cut yourself on a broken shard of bone or a possible lost arrow in the cavity. Use your headlamp and/or flashlight. Gutting by braille is a good way to hurt yourself.
There are a lot of things that dictate how you do this. Where the deer is shot may dictate if you go gutless or standard how far of a pack out and what kind of terrain. May be better off hanging the meat and coming back in daylight or if it's 70 yards down to the road drag it whole, down to take care of it in the headlights. How big he is and how steep it is . It is way more likely to get hurt trying to take a big load out in the dark especially by yourself. Also posting for help on here is liable to get a good response I know I would drive anywhere in snohomish county or south skagit to help a fellow member out of a jam especially getting them out safely.
I bring a bunch of extra lights in my truck. The ones that make me feel the best are three inexpensive led hanging shop lights that are less than a pound each. I go about 10 feet in three directions and then hang them facing away from me. Lights up the night all around me and let's me focus on what I'm doing. If I'm less than a mile from the truck, I mark the animal with a chem light that I always have in my pack, then go back to the truck for the extra lights. Field dressing with a headlamp can be tough. I cut myself doing it once, and now I also carry two cut resistant gloves in my kill kit that I wear underneath my latex gloves. Funny how the latex gloves always end up with little cuts that I don't feel with the cut-resistant gloves underneath.
