how can i obtain paperwork to obtain original united states citizenship issued prior to my service in the military

If you are able to remember details on your naturalization certificate, you or your lawyers can apply for an N-565 Application for Replacement Naturalization Document. Without specific information, it would be very difficult to fill out the application with an assurance that USCIS would be able to issue a replacement document. For purposes of sponsoring a family member, the law firm will also be able to use a copy of your US passport in lieu thereof.
