dig in well rotted manure . or compost . leaf mould
If you don't already have any of the above, which I'd recommend as first's, mushroom compost can be bought very cheaply from small nursery's for just over a £1 a bag and can be dug in.
All soil is wet at the moment so I wouldn't worry yet. It is too early to plant now anyway. Additionally raised beds drain well so as the weather warms and you begin growing crops you may find you need to water more frequently. I would leave all alone, let things settle and the worms begin their work and wait for the soil to warm for planting.
I would let it drain by itself, the lazy man's option. By their very nature raised beds are free-draining and it will very quickly dry out when the rain stops.
