You use the phrase "a variety of" to mean a number of different types of things. In this sense, as a collective noun, it's treated as a plural. As you usually use a plural verb after it, the correct sentence is:
A variety of toys are made at the company called ZYD.
This is a common confusion. One first must determine the subject of the sentence, since that is the word that determines verb agreement.
When a plural noun in a prepositional phrase follows a singular subject noun, the verb reflects the singularity of the of the subject noun. In the case presented, a variety is singular, therefore the verb form of to be should be singular (i.e., is). If the noun varieties had been used, the plural verb form are would be correct.
