a couple thoughts:

• I usually have a section called “Relevant Work” and another called “Other” where I say "Additional experience with [list my non-relevant jobs]"
• if you are taking time off from working, try to do something educational at the same time. classwork at a local university / community college is great, or do online classes or even a bunch of tutorials and/or an open-source/volunteer project. then you can say: “I always wanted to learn about (that topic) so I took some time off to really study it.” it’s most beneificial if it’s work-related, but it doesn’t have to be.
• present yourself in the best light, but do not outright lie on your resume because that might come back to bite you.
