Did your parents register your birth at the Dominican civil registry? If so you should be able to get a copy of your Dominican birth cert from any Registro Civil using the cedula number of either of your parents. Once you have that it is easy to apply for your cedula and passport. If they did not then you need to get a copy of your US birth cert, apostilled and translated into Spanish and take it to the JCE together with one of your parents cedulas to have a Dominican birth cert issued.
With that you can then get your cedula and passport.

Also you can do it all free of charge in the US.
What is required to declare children of Dominicans born abroad?
All children of Dominican parents are Dominicans provided that they are registered in the Dominican Republic. This registration process can be started without cost at any Dominican Consular Office considering that at least one parent is Dominican. Both parents must appear with the child at a Dominican Consular Office and must present the following documentation: a recent photograph of the child (size 2 x 2 inches, white background), Dominican Identity Card (Cédula) of the parents, Dominican Passport of the parents, Dominican Birth Certificate of the parents, Original Birth Certificate of the child issued by the Civil Registry Office where the child was born, Marriage Certificate if the parents are married to each other, one (1) Witness.
For the Birth Declaration to be duly registered, parents must request a transcript of the Birth Certificate Declaration given by the Consular Office at the “Junta Central Electoral” of the Dominican Republic. If the declaration is issued before the 60th day after the child’s birth it will be considered “oportuna”, after the 60 days “tardía”.
17) What is required of children of Dominican parents born abroad to acquire the Dominican nationality?
Option A: Declare the minor in a Dominican Consular Office and then request a transcript at the “Junta Central Electoral” of the Dominican Republic.
Option B: Request a transcript of the Birth Certificate issued by the Civil Registry Office in the country where the child was born.
Documentation requirements: Birth Certificatetranslated into Spanish and both the original and the translation notarized and Apostilled by the proper authority, Dominican Identity Card (Cédula) of the Dominican parent, Identity Card of the non-Dominican parent (if applicable), letter from the Dominican parent addressed to the “Junta Central Electoral” requesting the transcript of the Birth Certificate so that the child can acquire the Dominican citizenship.
This documentation must be presented for transcript authorization at the “Junta Central Electoral” in the Dominican Republic (located in the Plaza de la Bandera, National District). After paying the Transcript Authorization’s fee, you must choose a Civil Registry Office, where you want the Birth to be registered.
After 15 days you must pick up the Transcript Authorization at the “Junta Central Electoral”, and present it at the chosen Civil Registry Office for them to proceed with the transcript of the Birth Certificate. After paying the transcript fees you may request the Dominican Birth Certificate of the child.
In case the parents can not do the process personally in the Dominican Republic, a third person may be entrusted to conduct the process.
