Female Lug connector in Eagle
You can use a PCB-mount screw connector such as this one from Keystone (photo courtesy of Digikey): 



You will have to leave sufficient space between the connectors since there is nothing preventing the lug from rotating as there would be with a barrier terminal strip that others have suggested. 

Be sure to pick the correct size for the lugs you want to use them with. They are available in M2.5/M3/M4/M5/6-32/8-32/10-32. Refer to the relevant datasheet for the recommended hole sizes. 

You may also find this type useful if it is available in your desired size:



This kind is mounted right to the PCB so it requires more area, but it is made with an anti-rotation tab that engages the open end of your spade lug. Also by Keystone. 

Here, from this ebay listing, is a typical application (HVAC PCB) of the second type (some other connections are male spade connectors soldered into the board).
