California has a number of forms to assist you in seeking order. The ex parte request would be the FL-300 (Order to Show Cause cover form) the FL-205 (Temporary orders - they're not called "ex parte" orders) and the FL-310 (Application pages). You will also have to provide your declaration giving the facts about what has been going on and why you need the ex parte/temporary orders.
You can request immediate orders for contact, but even the most capable of experienced family law practitioners would not likely be successful unless able to make a compelling showing of immediate and irreparable harm to your child. What you need to be considering is whether finding her in contempt will solve the underlying problem, which is that she will apparently do anything to interfere with your relationship with your child and avoid sharing the child with you. For that assessment, nothing short of the advice of a local experienced family law practitioner will meet your needs.
Best wishes for a favorable outcome, and please remember to designate a best answer.
