Iceland in the fall can be tricky to pack for. I visited in early October and we had about 10 hours of sunlight. While we were there, the temperature was usually the mid 40's; we only had one day in the 30's with lots of extreme winds/rain, but the rest of the days were actually pretty dry and sunny!
I brought 3 of my bags for this trip. I had my Osprey Tempest 40 to carry my boots, clothing, and accessories. I also brought my Kanken Mini and packed it full with my drone and its accessories. I then place my Kanken Mini inside my Kanken Classic

Technology
Phone
In-ear Headphones
Camera and/or GoPro
Drone + controller
Drone Batteries - I de-charge them to 50% and store them in Lipo-safe bags
Portable Chargers (2) - Definitely pack a few of these because the car may only have 1 USB port, so you'll need to provide your own way to charge if there are lots of people in the rental car
MicroSD Cards - Bring a MicroSD card holder to keep organized
Travel Plug Adapter - If you're from the US you'll want to buy a few of these on Amazon so you can use the outlets there!
Other
Hairbrush
Makeup
Makeup Remover Wipes
Sleep Mask - necessary for those overnight flights there
Water Bottle - the water in Iceland is so pure, even from the sinks, so you'll need this for your long days out traveling!
Ibuprofen
Detoxy+ supplements - These are great for digestion, so you can prevent bloating during your trip
