I took a 40mg Vyvanse (lisdexamfetamine) tablet a week ago tomorrow. I have a pre-employment 10 panel urine test tomorrow afternoon, will the Vyvanse (lisdexamfetamine) appear on the test?

Not likely. It is unlikely that vynase will eve be tested for. See this site for the usual drugs included in the screen in the 10 drug panel. http://www.drugs.com/answers/drug-test-10-panel-urine-test-consist-testing-701515.html.
