Hi there. You can sow Lupin seeds now, although they may not flower this year. There is no need to soak them.
I sow mine into modules [ a seed tray that is divided into smaller sections; I would use a 15 module tray. ]
I would start them off on a window sill, then move tem to consevatory once germinated.
You will need to transplant into bigger pots as they grow.
When they are a few inches high, the pots can go outside.
I would not plant them in the garden till they are at least 6 inches tall, as that will increase their chances of survival.
You may be wise to cut off any flower stalks that appear this season, as that will give you stronger plants for next year.
Hope that helps, seeds really want to grow.
