I wouldn't think they need watering at the moment - stick yoru finger in the soil about an inch - if it's bone dry down there then water, if not leave it alone. They don't need a lot of water in the winter as the leaves are not giving off moisture in the cool weather. They'll need more in the summer.
My bay tree is in a large terracotta pot in a mix of John Innes No 3 loam based compost, with about 1/3 horticultural grit added. The pot is stood up on feet to aid drainage.
I bubble-wrap the pot in the winter as it's too big to move into a sheltered corner.
