Be totally honest with the recruiter.  Tell them everything.  Good and bad.  It’s not our place to chastise you, but we need to know the truth about everything.  Whether it’s your base salary, your potential bonus, your education, your job description, your dates of employment — be sure to share it all (even why you were let go).  Recruiters are paid to find out, so we would rather hear it from you rather than from another source.  A good recruiter will double-check everything and if something doesn’t jive, there will be consequences.  Also have your resume littered with accomplishments not just day to day job responsibilities.  Tell about your successes and impactful differences you’ve personally made.  And, God’s sake, don’t take credit for someone else accolades.  We’ll be checking those facts, too.
