If you are not getting any strikes slow down yourprobably going to fast. Make sure that you make bottom contact. Then use slow, methodical twitches of your rod to work the lure. Maintain contact with the bottom and with your lure. Bass usually don't strike very hard during the winter and it's easy to miss a strike.
Most bites feel like a very slight pluck of the line or just an increase of resistance.
I wear insulated overalls, a down vest, insulatedboots, a skiing hat, and a warm parka. Carry spare clothes. A boarding ladder is not a necessity but would be very nice if you ever fall in. I always bring a thermos of hot coffee to help warm meup. If I start getting cold I get off the water immediately.
