It depends on the application you are using.
The best way is to work with an illustration package such as Corel Draw or Adobe Illustrator but I think you can also do it in Photoshop.
The general idea is to set a gray color to letters outline, set the fill color to white (or transparent) and apply an appropriate shadow effect.
