I have a pair of Fox Dirtpaws that I use with my MTB and work with touchscreens, and they would mostly fit the bill for what you are looking for. They won't be super warm as they aren't a winter glove, but they are comfortable and would probably do.

I have a great pair that work with my dual sport too, but you don't want motorcycle gloves. They too aren't always that warm either, they are expensive and usually because of the protection they are stiffer. Way overkill for what you want.

As a bonus tip, if you find hands getting cold in mountain bike gloves, or any other glove for that matter, you can wear rubber gloves underneath them and that really helps. If you have naturally sweaty hands it might not work as good though. For touchscreen use, just cut a bit off the palms of your fingertips, so the touch will still work through the gloves.
