For smaller quantities it's definitely worth following Lilli's example of using a bulb basket or similar.
I also use pond mesh baskets as I have some extra of those.
For large plantings the baskets become a bit unpractical as you really need a lot of them. Have a look at the third pic in this blog post from Fluwel to see a nifty tool that you can use to remove the soil and reveal the bulbs:

I don't have such a nice tool with handles and I don't think you can buy these, but this year I experimented a bit simply using a piece of wooden board without handles to scrape of the topsoil and I thought that worked very well. My board has rounded edges as to not hurt the bulbs too much. Really seems to be a time saver, but I still need to experiment a bit more with this. So far I only tried it on crocuses as I had some of those I wanted to move. Might be worth giving a try if you have the bulbs planted roughly at the same depth and your soil isn't too hard.
