Several ways to do this, all of them covered numerous times in the forum. I'm a fan of doing something like this for 16 bits or two bytes (from here you can work out the for loops and counters required) 
 nus_to_send_array[0] = (Array[0] & 0xFF00) >> 8;
nus_to_send_array[1] = (Array[0] & 0x00FF);
...
nus_to_send_array[18] = (Array[9] & 0xFF00) >> 8;
nus_to_send_array[19] = (Array[9] & 0x00FF);

ble_attempt_to_send(nus_to_send_array, sizeof(nus_to_send_array));
