This is the approach you don't need to use padding, just set the height and width for the a and let the flex handle with margin: 0 auto.

.social-links a{
  text-align:center;
	float: left;
	width: 36px;
	height: 36px;
	border: 2px solid #909090;
	border-radius: 100%;
	margin-right: 7px; /*space between*/
    display: flex;
    align-items: flex-start;
    transition: all 0.4s;
    -webkit-transition: all 0.4s;
} 
.social-links a i{
	font-size: 20px;
    align-self:center;
	color: #909090;
    transition: all 0.4s;
    -webkit-transition: all 0.4s;
    margin: 0 auto;
}
.social-links a i::before{
  display:inline-block;
  text-decoration:none;
}
.social-links a:hover{
  background: rgba(0,0,0,0.2);
}
.social-links a:hover i{
  color:#fff;
}
