Given that $F_{1}$ and $F_{2}$ are the left and right foci of the ellipse $\frac{x^{2}}{a^{2}} + \frac{y^{2}}{b^{2}} = 1 (a > b > c)$, respectively, $A$ is a point on the ellipse located in the first quadrant, and $O$ is the origin. If $\overrightarrow{OA} \cdot \overrightarrow{OF_{2}} = |\overrightarrow{OF_{2}}|^{2}$ and the eccentricity of the ellipse equals $\frac{\sqrt{2}}{2}$, find the equation of line $OA$.
