Make sure it's easy to read for the speakers (i.e. the font is 12pt or bigger). I like to use 3 double-spaced columns per page. You could also number the words.
If the list is long (more than 2 pages), number the pages to avoid confusion and add titles for each part of the list (stimuli for AX, stimuli for lexical decision). If they read the titles, this could help you later when cutting the sound files.
Oftentimes the last word of a list is said with different intonation (a final fall); repeat this word earlier in the list or at least have it be a filler.
Print the recording list one sided, or make sure they don't turn the page while speaking, since this will be audible.
